Hosted on the website for the upcoming Watchmen film, the Watchmen arcade game is - despite its "1977" production date - a decidedly 80's take on the side-scrolling beat-em-up, and features two of the original Minutemen (the team's predecessors) walking down streets and kicking trash cans.

It won't win any awards for innovation, but for something that's free, it does a great job of capturing both the feel of the comics and the shrill soundtracks to the games of the mid-80s.
